Answer:
$64
Step-by-step explanation:
Okay so all you have to do to get the sale price is multiply the original price by how much percent of that price you still have to pay.So in this case you still have to pay 80% of the price since it's only 20% off.So all you do is multiply 80*0.80, and it equals 64.So $64 is the sale price.
Here is another example just in case you still don't know how to do these problems.Let's say the original price of a watch is $80, and the store is having a 50% off sale.To get the sale price all you do is multiply 80 by how much percent of the price you still have to pay or in this case is 0.50 which equals $40.
